JOHN G. CHAPMAN, OF DOWNEY, CALIFORNIA.

AUTOMATIC STOP FOR WENDNHLLS.

SPECIFICATION forming part of Letters Patent No. 369,587, dated September 6, 1887.

Application filed March 24, 1887.

TU LZZ whom t may concern.l

Be it known that I, JOHN G. CHAPMAN, a citizen of the United States of America, residing at Downey, in the county of Los Angeles and State of California,`have invented certain new and useful Improvements in Automatic Stops for Vindmills; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon., which form a part of this specification.

My invention relates to certain new and useful improvement-s in tank-regulators, the object of my invention being to provide a means whereby the vanes of a windmill can be closed or their source of power cnt oft" automatically when the tank is filled to a certain level, and whereby, when the Vwater in the tank falls below the desired level, the source of power will be connected to the piston-rod of the pnmp,so

. that water will be pumped into the tank,.as

will be hereinafter set forth.

Vith the above end in view my invention consists in the construction and combination of the parts, which will be hereinafter fully set forth,and specifically pointed out in the claims.

In the accompanying drawings,which illustrate myinvention, Figure l is a front viewof an automatic device, showing the means for automatically cutting oft" and starting the source ot' power, constructed in accordance with my invention. Fig. 2 is a side view, and Fig. 3 is a detail perspective view. Fig. 4 is a perspective view of the devices shown in Fig. 3, but looking from the rear.

A and A refer to two suitable uprights, which may form, if desirable, the supporting means for 1f-windmill, and between these uprights is located a pump-stock, B, which isprovided with a suitable spout, B,which extends over-the edge ofa tank; and this pump-stock, above the spout B, has attached thereto a suitable stand-pipe, B?, through which the pistonrod b ofthe pump passes. The post or standard A is provided on one side with an outwardly-proj ecting arm or bracket, O, of any suitable construction, to which a lever, D, is pivoted, said lever carrying at its short end an adjustable weight, d, which may be attached Serial No. 232,300. (No model.)

thereto in any suitable manner. The opposite end of this lever D carries a tank, E,which is provided with an opening, e, to which is conu nected a flexible tube, E. This tank E is also provided With an opening, e, which islocated as shown in the accompanying drawings. 'The post A has attached thereto a guide-strap, b', the ends of which serve to limit the movementofthe lever. The flexible tube E is connected in any suitable manner to the branch spout B at a point between the pump-stock and a valve or turn-plug, b2, which is located therein.

F refers to a rod or bar, which is connected at its upper end to a suitable means for operating or turning the vanes of a windmill, so as to open or close the same, or said rod may connect with any suitable means for connecting or cutting oft' the piston-rod of the pump from thesource of power or driving means; and the rod F is provided at its lower end with a chain or flexible connection, the opposite end of which is attached to the lever D. The rod F may be continued so as to extend to a hand-lever, F', which is preferably located at a point below the pump-stock, this handlever having connected thereto a chain, f, which connects with the section f of the rod F. .By depressing the handlever the vanes of the windmill may be closed or the other source of power cut ott' or disconnected from the piston-rod of the pump. ',lhespoutbranch of the pump is provided with a valve or plug, b", and to the projecting stem g, which is prei'- erably rectangular in cross-section, is attached a plate, G, which is provided with a projecting arm or arms, GQ which extend over the valve-casing and contact with the saine, J

so as to limit the movement ofthe valve-stern to a quarterturn. rPhe outer end of the valve-stein beyond the plate G may be circular in crosssection, so that the weighted lever H will swing upon the point which connects it with the valve-stem, and this weighted lever is cut away, so as to provide a shoulder, h, which will abut against the plate G to turn the stem.

I refers toa rod, which is suitably bent, one end thereof being pivotally attached to one of the standards or posts, while the other end is rigidly connected to a fioat, J, and this rod I is connected by a suitable flexible connection,

j, to a pin7 i, which extends from the short end of the weighted arm H.

The outer end, i', ofthe pini is bent to project at right angles with the Weighted arm H, and when this arm occupies its vertical position, with the plug turned to permit discharge of' water through spout B', said bent end t" stands in the path of a crossbend, I', of rod I, so that at the moment the water in the tank reaches the desired level the rod I, carried upward by the float, will strike and lift bent end i of pin i, thus throwing the weighted arm H past the center and causing it to drop to the position shown in the drawings to shut off' the water-supply.

The operation of my invention is as follows: When the parts are organized as shown in I of the accompanying drawings, the device will be in a position so that the pump is not operating. In the reverse position-that is, with the bar H standing vertically, as in Fig. 4c-after sufficient water has been pumped into the tank to raise the water to the desired level, the float will rise, which movement will be communicated to the rod I, which will rise until it comes in contact with the projecting arm z', which is attached to the weighted bar H, and by contacting with this projecting arm it will throw the weighted bar from a rearwardly-inclined position to a position beyond its vertical center, so that said arm will fall, and in falling will contact and carry with it the plate G, thereby closing the valve, so as to cut off the supply of water through the spout ofthe pump. As the reciprocation of the pistonrod still continues, the waterwill be raised in the stand-pipe B2 until it reaches the level of the receptacle E, when it will enter the same, and after the same becomes partially filled it will overbalance the weight of the opposite end of yits pivoted supporting-bar and draw upon the rod F, which cuts off` the power from the piston-rod. When the water in the tank falls below the desired level, the float will fall, and,owing to the flexible or chain connection between rod I and bar H, the latter will be `forced to a vertical position and the valve automatically opened, when the water will flow through the iieXible tube F/ from the tank E, out through the pump-spout, and then the weight will carry the lever to the position shown in full lines and permit the rod Fto move so as to again communicate the power with the piston-1od.

By the use ofthe hereinbefore-described device the water may be maintained at a level in the tank automatically.

l. The combination, in adevice for regulating the depth of water in tanks, of a receiving-tank, a pump, a ioat arranged within the tank, a supply-pipe having a valve adapted to be operated by the float, a lever carrying a receptacle at one end, and a iiexible tube connecting the receptacle with the supply-pipe, whereby when the water falls below a certain level iu the tank it is caused to ow into said receptacle to disconnect the motor from the supply-pipe, substantially as described.

2. In combination with a pump or other water-supplying medium having a valve located in the.dischargespout, a power-transmitting device connected with the pump, a lever provided at one end with a receptacle, a flexible tube connecting the receptacle with the pump, a tank, a float therein provided with a rod adapted to operate the valve, and a rod connecting the lever with the power-transmitting device, substantially as described.

3. In combination with a pump having a valved discharge-spout, a valve-operating lever and tripping-bar carried by the valve stem, a lever provided at one end with a receptacle, E, a flexible tube connecting said receptacle and the spout, a stand-pipe communicating with the spout and flexible tube, a float connected to the valve-operating lever, and a rod, F, connected at one end to the receptacle-carrying lever and at the other end with the power which operates the pump, sub'- stantially as described.

4. In combination with a pump having a valved spout, a stand-pipe extending above and communicating with said spout, a pistonrod, b, a pivoted lever, D, provided at one end with an adjustable weight yand at the other end with a receptacle, aliexible tube connecting the receptacle with the spout, a rod, F,

connected' at one end to lever D and at the other end with the power, and a fioat provided with means to operate the valve of the pumpspout, substantially as described.

5. In a device for maintaining a uniform level in tanks, the combination of a pipe through which the water-supply passes,v a valve located in said pipe and provided with a plate, G, having an inwardly-projecting arm, G', for limiting the rotary movement of' said valve, aweighted arm, H, pivoted to the valve so as to contact with plate G, and provided with a projecting arm, a float provided-witha rod, I, and connection j, wherebyl the valve is opened when the iioat falls be low a certain level and closed when the water rises above a certain level, substantially as described. A6. The combination, with a Water-supply mechanism for `tanks and a supply-pipe, the valve of which is connected with and controlled by a float, of a lever, D, provided at one end with an adjustable weight and at the other with a receptacle, a stand-pipe connected to the supply-pipe, a flexible tube connecting the receptacle with the supply and stand pipes, and a rod, F, connected at one end to the lever D and at the other end to the pumping mechanism, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses. t
